other soft materials like chamois soaks.

the screen causes deformations and colour fading.
Poor Picture • Have you selected the correct TV system in the manual installation menu?
• Is your TV or house aerial located too close to loudspeakers, non-earthed audio
equipment or neon lights, etc.?
• Mountains or high buildings can cause double pictures or ghost images.
Sometimes you can improve the picture quality by changing the direction of the
aerial.
• Is the picture or teletext unrecognisable? Check if you have entered the correct
frequency. See Installation, Manual installation, p. 6.
• Are brightness, sharpness and contrast out of adjustment? Select Factory
settings in the Setup, General menu, p. 8.
No Picture • Are the supplied cables connected properly ? (The aerial cable to the TV, the
other aerial to your recorder, the VGA cables to the display, the power cables.)
• Has the child lock been switched off ?
• Is your PC switched on ?
• Do you see a black screen and the indicator in front of the TV lights up blue,
this means that the display mode is not supported. Switch your VGA-source to a
correct display mode.
• In case of weak or bad signal, consult your dealer.
Digital distortion The low quality of some digital picture material may be the cause of digital image
distortion. In this case select the Soft setting using the Picture menu, Smart Picture,
without changing the picture settings manually.
No sound • No sound on any channel? Check the volume isn’t at minimum.
• Is the sound interrupted with the mute key ¬?
